|MPnovED SKATE.

Spccifiation` forming part of Letters Patent No 47.1 85, dated `April 11,1855; 1

To all whom it may converge: I

Be it known that l, DANIEL S; BRIGHAM.`

ot' the city and county of Worcester, and State of Massachusetts, have invented certuin new and useful Improvementsin Skates;

and I do hereby declare that the following is a full, clear, and Vexact description of the ,consltruction'and operation ofthe same, reference being had to the lac :companying, drawings, in whieh 1 1 1 Figure 1 represents a perspective View '0f said skate. Fig. 2 represents -a side view of the same, sho-wing the manner in which the skate is secured `to the boot. Fig. 3 repre4 sents a detached viewgh'ereinafter to be re fcrred to.-

To enable others skilled in the art to makeV hndLuse iny invention, I will proceed to describe its construction and operation.,

A and B represent two plates on which the heel and sole of the foot rest.' They are` con nected by a longitudinal piece, U.

D represents the runner, which is 'secured to the plates A B by means of the screws a or otherwise. The shape of the runner is shown on -the drawings; but its form may be modified audits heel may be made angular instead of round, as shown by the red lines' at b in Fig. 2. The formation of the runnerj as shown makes the bottom-part thereof to a f certain'degree elastic, for purposes hereinafter g to be described.

E represents a clamping-bolt, which is rig# idly secured to the heel-plate jA by means of a screw-nut, c; and Gr represents a similar clamping-bolt, which is rigidly secured to the clamping-lever H, butfwhich ,turns loosely within 'the plate I3. Each ,of the clampingbolts is provided with flanges 2, which,1when inserted into the oblong slots d, Fig. 3, of the' plates h, attachedto the sole K and AAheel I of the boot, can .be secured to said plates by turning them an angle 'of ninety degrees or a quarter of a revolution,'the anges 2 catching the inner edges of the plates h within the slot d. This construction of the skate presents `great facilities in secnringit to the boot or shoe in a firm and rigid manner without using any straps whatsoever, which are so annoy? ing to the skater, as they not only check the circulation ofthe blood and pain the feet, but lalsostretch and become loose. y

In applying my skate to the boot or shoe,

of the slots d correspond in distance fromleach the latter 'has only tobc1provided theheel j and' sole with the platesli, lwhieh are secured). 11 1 thereon in such a mannerthatthe positions.` `1` other with that of the clamping-bolts@ G. di

The heel-bolt E is then` isertedinto 'the heel-1,1` o y i plate h by holding the.skate; atgright angles v, 1

withV the sole of the" boot, ,and becomesiirmly; `1

The leverH inthis position maybe f1 secured by means ofthe thumb-screw g, which; 1 enters a hole, n, in the pieceV G, or by'nieans `1` t `1 of a spring properly applied@ -Tof preventany i 1 longitudinal movement Lof` theskate-` byfgea-` j son of the slipping of theheads of theclainp-fj 1 bolts within the. cavities'in the sole or, heel, I` 1 provide the heelboltE`with a point, o,gwhich,1 1

L represents an `adjustingscrew, which 1 i V works in theclampflever H, fand lwhose stelnj 1 1 1` extends to thebottom part ofthe runner D, 1 i and can enter a small :cavity therein to keep i it in its vertical position l, Byturning its head i1 1 m the bottom part, D, ofthe runner'is forced 1 i outward so as to be made` crowning, as repre-,'-` i sented inred lines at Fig.` 2, and wheninthat1 1 y ,o position the runner is in contact w'itlrth'e` iceq` at its center part only, andI willthns enableh l` the skater to turn veryjshort curves, thereby ,y adding much to the pleasure i of .skatingzfl 1 When the screwLis tuned'1npward,1the bot-1` 1 tom part of the runner. becomes straight1 1 1 again, and is' in,contaetwithgtheiieelnearlyl i 'through its entire length.` v f 1 The clamping-leverl may'beapplied to the 1 1 v i Aheel-bolt' E instead; `of Ltothe boltG, andjin 1 1 that case the latter must be rigidly sk aenljedio` 1 o v its plate.
